CARPET STRETCHER AND TACKER.

SPECIFICATION forming part of Letters Patent No. 467,864, dated January 26, 1892.

Application iiled May l1, 1891. Serial No. 392,280. (No model.)

T0 @ZZ whom, t may concern.-

Be it known that I, MARTTN PEAEsoN, acitizen of the United States, residing at Robbinsdale, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in a Combined Carpet, lVire-Cloth, and Canvas Stretcher and Tacker, of which the following is a specification.

This invention relates to implements employed in stretching and tackin g carpet, wirecloth, canvas, dsc.; and it consists in the construction, combination, and arrangement of parts, as hereinafter shown and described, and speciiically pointed out in the claims.

In the drawings, Figure lisasectionalside elevation. Fig. 2 is afront elevation. Fig. 3 is aplan View in section on the line X X of Fig. l. Fig. 4 is a rear elevation on the line Y Y of Fig. l. Fig. 5 is a plan view in section on the line Z Z of Fig. l. Fig. 6 is a cross-section of the tack-feeding hopper on the line V V of Fig. l, all the above views showing the construction of the implement when employed as a combined carpet-stretcher and tack-driver. Fig. 7 is a cross-sectional view on the line IV lV of Fig. l, illustrating the construction of the nail-feeding trough or chute. Figs. S and 9 are views similar to Figs. l, 2, and 3, illustrating the slight modication in the construction of the implement necessary to adapt it for use in attaching wire-cloth, canvas, or other material to screens, frames, and in similar locations.

A is the base-frame of the implement, to which the stock A2, supporting the tack-driving plunger A3, is attached, as shown.

When employed as a combined carpetstretcher and tack driving implement, the base A will be made somewhat broader, as shown in Figs. 2, 3 and 4, than it will be when employed as a combined wire-cloth or canvas stretcher and tacker, as shown in Figs. S and 9; but in both forms the front edge of the base-frame will be armed with small teeth a, to engage the fabric in the ordinary manner of carpet-stretchers and similar implements.

I'Vhen used as a carpet-stretcher the teeth a will generally be set pointing forward and slightly downward, while in the other form they will generally be formed pointing downward, as shown, respectively, in Figs. l, 2, 3, and 4 and in Figs. 8 and 9.

The plunger A3 is adapted to be held normally in its upward position by a spring A4. Attached to one side of the stock A2 isa nailfeeding chute consisting of two parallel metal strips d d2, secured toarib b, projecting from the base A and extending outward and upward at an angle from the stock and with outwardly-iiaringsidewingsddtalongtheirsides, as shown. The feed-hopper B is connected to the upper end of the feed-chute, which is formed with a somewhat contracted outlet e' leading downwardinto an inclined receiver c2, which is formed to lead the tacks into the feed-chute. The bottomof the feed-hopper is formed into two compartments e2 e4, rising toward the exit-slot e and provided with a guard-strip e5, the construction being more clearly shown in Fig. G, which represents a cross-section of the feed-hopper. By this arrangement when the tacks are placed in the hopper they are retarded somewhat and fall into the receiver e2 below the outlet c a few at a time and only when'the implement is shaken slightly, thereby insuring the tacks automatically arranging themselves in regular order in the feed-chute, as shown at g in Fig. l, the lowermost tack g in the chute resting against a pivoted stop-lever, as shown.

fi t2 are slots formed through the sides of the stock A2, and through which the ends of a pin t3 (passing through the plunger A2) project, as shown. Pivoted at 4 to the side oi' the stock A2 alongside the slot i2 is a leverarm It', whose upper end h2 lies alongside the projecting pin t2, while its central part h3 is curved inward and overlapping the slot, so that when the plunger c2 is forced downward the pin i3 will force the lower end of the lever 71. to one side. The lower end hnl of the stoplever It is curved around and ends opposite a cavity in the chute d d2, as shown in Fig. l, where it is held normally by the pin 713 in its upward position, as shown in Fig. e. Attached by a screw h5 to the lever h is a small curved finger 7L, adapted to enter a cavity in the chute from the opposite side to the point h4, but farther from the stock A2, so that a space a little more than the thickness of a tack occurs between the adjacent ends of the fingers. When the lever 7L is in its normal position, as shown in Figs. 1 and 4, the end of the finger h4 will end at the outside edge IOO sisY

of the cavity in the feed-chute, but the end of the finger h6 reaches across the cavity and forms a stop to the further progress of the tacks. When the plunger A3 descends, the pin i3 forces the lower ends of the lever 7L to one side and reverses the position of the fingers h4 h6, causing the finger h6 to withdraw from the chute, and causing the finger h4 to be forced into and across the chute. Then when the plunger rises again the pin t3 will act upon the upper end h2 of the lever 7i (which has been thrown acrossthe upper part of the lever) and return theleverto its normal position, this action automatically feeding theV h by the screw h5 it may be adjusted to v adaptthe-implementto different sizes of tacks.

D" D2 are two parts of a spring-jaw running parallel to each other and embracing the lower end-of the chute d d2and held bythe rear end atD3 in the standard M onthe'v rear of the4` chute and projecting through the front of the stock A2as shown at m. m2. Attached to or formed i-n one piece with. the stock A2 is a plate A5havin g two outwardly and dow-nwardly curvedslots 'm3 m4, in which the free ends-m m2 of the-spring-jaw'D" D2move up and down. The jaw D D2 rests normally in its upward; position beneath thelower endof the plu-nger A3, and is provided at this point Vwitlr small cavities m5, adaptedtoreceive and support the heads of the tacks as they fall into-'place between the parts of the springjaw when released by theaction of the lever h', one of the tacks being shown in position ini Fig. 1'. The slots m2" m4 run downward in parallel perpendicular lines for a short distance and then turn sudden-ly outward in opposite directions, thez function of the slotsbeing to-separatefthefparts D D2 to permit the plunger A2 toV pass down between them-.and drive-the tack home. The springjaw tlf-us serves tov` hold, the tack until the plunger in its downward movement sets. it

partially into the floor or other part adapted tol-receive it,y and then moves out of the way to: release the head of the tack and permit the lower end of the plunger topassithrough and drive the tack home. A small wedgeshaped chock m6 isattached to the baseA .between the slots m3 m4 to assist in forcing the. parts D D2 apart and rend-er their action morewcertai-n. As soon as the plunger is-thrown upward again by Ythe spring A4 the' springjaw returns, also, to-its normal position ready toreceive the next tack, which is fed to i-t automatically by thev action of the lever 7L and itsngers h4 h6.

A spring-guard N is attached to the stock A2 orvother fixed part of the implement and projects over the top' of the-chute d d2 to rest above thehead's of the tacks as they pass down the chute and prevent 'them from jumpclogging it. of the slot by the movement of the lower end ing out of the chute by any jarring motion of the implement.

A guard P is shown hinged by one end t in the chute d d2 and lying loosely therein with its free end above the slot in t-he bottom of the chute, and with a notch t2 just large enough to permit the passage of vthe heads of the tacks, the function of this guard being to stop any tacks which do not arrange themselves in regular order and prevent them from running down into the feed mechanism and In Figs. 8 and 9 a second one of these hinged guards P2 is shown ina reversed position, the outlet end of the chute to assist in properly guiding the tacks into the chute, and one of these secondary guards may be placed in theI form of' imp-lement shown in Fig. l,` if desired;

In the forni shown in Figs.- S and 9 the chuteis shown continu-.edupward in the form of a tube d5 before it'l unitesy with the feedhopper B', which tubewill be utilized as a handlel to hold the implement by and will be provided with grip-piecesd.. This form of hand le will be mostV convenientwhen the implement is employed asy a wire-cloth or can- `vasi stretcher and tacker, while the form shown in Figs. l and 2 will beimost convenient when employed asa carpet stretcher and tacker.

A small agitatorR'f'issliown attached to the hopper B in Figs. Si and 9, and.- adapted to be actuated by a-spring finger-leverv R2 to agitate the tacks as they runfrom the receptacle c2 and assist in feeding theminto the tube and chute- One of these agitators` may also be attached tothe-outlet of the hopper when the implement show-n in. Figs. l, 2, and 3 is employed, if desired.
